Summary

tDCS can modify the attentional response of patients with fibromyalgia. Methods: This study deals with a randomized, blind, crossover, controlled tDCS-sham. The sample will consist of 40 patients, divided into two groups with sham interventions and active crossover.

Detailed description

Check that the tDCS can modify the attentional response of patients with fibromyalgia. Methods: This study deals with a randomized, blind, crossover, controlled tDCS-sham. The sample will consist of 40 patients, divided into two groups with sham interventions and active crossover. Patients answer the questionnaires in order to verify the Psychological Factors and Clinical. Will use the Impact of Fibromyalgia (QIF), Pittsburgh Sleep Questionnaire, Conditioned Pain Modulation (CPM), Beck Depression Scale II, Catastrophic Scale , Go noGo Test, Attention Network Task (ANT) to verify the ability attentional as well as to verify the Near-infrared spectroscopy (NIRS) brain oxygenation. They will be used before, during and after the intervention with tDCS. Intervention with tDCS or sham will be held in a single session. Expected results: It is expected that fibromyalgia patients undergoing tDCS present, after the intervention, improved attention capacity .

Conditions

• Fibromyalgia

Interventions

Type	Name	Description
DEVICE	Transcranial Direct Current Stimulation	The intervention session with tDCS lasts for 20 minutes. tDCS uses rubber electrodes that are within sponges that are moistened with saline. These electrodes are placed on the participant's head. Through these electrodes will pass a weak electrical current that can at most cause mild itching at the site where the electrode is positioned. The generated electric current is equivalent to a small common battery that we use to run toys or radios. The procedure does not require that the patient be subjected to shocks, cuts or surgery. The participant will receive active tDCS or placebo, but receive both types of intervention during the performance of the two sessions.
